Every once in a while, I get this error when connecting to a server:

RE_Shutdown( 1 )
Shutting down OpenGL subsystem
...wglMakeCurrent( NULL, NULL ): success
...deleting GL context: success
...releasing DC: success
...hiding window
...destroying window
...window successfully destroyed
...resetting display
...shutting down QGL
...unloading OpenGL DLL
-----------------------
MSG_ReadDeltaEntity: unrecognized entity field type 23283 for field 201


Anyone have any ideas?

OpenGL needs to be installed on your computer. However, if you've been playing the game, that isnt a problem. I've received this error as well, and think it is more SERVER related then anything else.

I've gotten that error a few times as well. Join a different server instead.
